electroweak interaction: symmetry breaking

Strongly interacting dynamics and the search for new physics at the LHC

We present results for the spectrum of a strongly interacting SU(3) gauge theory with Nf=8 light fermions in the fundamental representation. Carrying out nonperturbative lattice calculations at the lightest masses and largest volumes considered to …

Stealth Dark Matter: Dark scalar baryons through the Higgs portal

We present a new model of stealth dark matter: a composite baryonic scalar of an SU(ND) strongly coupled theory with even ND≥4. All mass scales are technically natural, and dark matter stability is automatic without imposing an additional discrete or …

Composite bosonic baryon dark matter on the lattice: SU(4) baryon spectrum and the effective Higgs interaction

We present the spectrum of baryons in a new SU(4) gauge theory with fundamental fermion constituents. The spectrum of these bosonic baryons is of significant interest for composite dark matter theories. Here, we compare the spectrum and properties of …
